This has gone quite far enough. Thus far Alfirin has only murdered people over it where the law gave her a reasonable excuse to, but that's still at least one person dead who didn't have to be.
The Church can keep its secrets. It cannot keep his.
To the people of Westcrown and all the Iomedaen faithful of the world:
Recently word has reached me of the publication in Westcrown of a section of the Acts of Iomedae previously lost in this age of history, concerning Alfirin the ally and companion of the eventual Goddess, and of the rumor and speculation that has proliferated in its wake. I write to the people of Westcrown concerning the truth of these rumors, that they may not in repeating them inadvertently promote heresy or dissent within the Faith of Iomedae.
It is already known to some of you that I was born more than seven hundred years ago, in the year 3951 A.R., having been turned to stone in the thirty-ninth year of my life by an ancestor of the diabolical Thrunes, and returned to life only with the recent downfall of that House. I have been a follower of Iomedae my entire life and am intimately familiar with the text of the Acts as it was in that ancient era, before any deletions or modifications had been made, and am also somewhat familiar with the secular history of the Shining Crusade commissioned and authorized by Iomedae herself, now altogether lost. The accuracy and integrity of my memories, up to a reasonable expectation of mortal fallibility, has been confirmed by the Goddess Iomedae herself via Commune with a priest of her Church.
It is by this authority that I tell you that the recently published passages, although genuine as the Church affirms, are incomplete, and misleading in their incompletion: in truth, Alfirin returned to the service of the Shining Crusade a handful of years after the end of her personal relationship with Iomedae. She became an archmage shortly after the death of Arazni, and was the close, invaluable, and trusted ally of Iomedae throughout the entire period that the latter was Knight-Commander of the Crusade, although no hint of personal intimacy between them is recorded in any history with which I am familiar. She departed Iomedae's service immediately after the defeat of the Whispering Tyrant, and appears no more thereafter in any history, nor do I know anything of her later activities or ultimate fate that has not been designated secret by the Church of Iomedae.
Neither the Church of Iomedae nor I disapprove of amorous relations between women in their generality. However, the use of the term 'Alfirinic' to refer to such relations, and the veneration of Alfirin as a Chaotic Good goddess of the same, strike me as both dangerous to the integrity of Iomedae's faith and insulting to the memory of a cherished friend and ally of the mortal Iomedae. In truth there is no evidence that she was any more concerned with such than any number of women even within the armies of the Shining Crusade, and I can say with rather great certainty that she was neither Chaotic Good nor a god. Her alignment is not known to history, owing to her long habit of concealing it carefully even from her closest allies, but the consensus of historians in the era of my birth was that she was most likely Lawful Evil, although she is not recorded to have committed any obviously iniquitous acts. Furthermore, while her ultimate goals and motives were obscure, she had at times made known her general opposition to the power that the gods wield over mortal kind. It is possible that she ascended to godhood at some point to further her own strange purposes, but I think it unlikely that, even in such case, she would wish to be worshipped.
I swear before holy Iomedae, and before all the gods of Law and Good, and upon my own honor, that all these words here written are true.

He might be putting himself in danger by writing this, of course, but his own model of Alfirin is much less moved to murder by the revelation that she existed as an Evil archmage than by speculation that she's a Chaotic Good goddess of love.
